New experimental findings bolster Stephon Alexander's 2006 theory that suggested that Chern-Simons gravity could also potentially solve one of the biggest mysteries in cosmology: why our universe contains more matter than antimatter. Alexander's theory predicted that the Chern-Simons interaction could have yielded a relative abundance of left-handed gravitons, which would, in turn, preferentially create left-handed matter over right-handed antimatter.
